225352 divided by 80 
The aim is to understand the frequency of 80 in 225352.

Advancing to step 1:
If we divide 2 by 80, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 80

Step 2:
80 goes into 22 0 times with a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 80

Step 3:
The number 80 fits into 225 2 times, leaving a remainder of 65.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 160 from 225 and we're left with 65.
Take the next digit (3) from the dividend and append it to 65, then repeat: 653 / 80

Going ahead to step 4:
When dividing 653 by 80, we get 8 with a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Subtracting 640 from 653 leaves us with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 80

Let's proceed to step 5:
135 divided by 80 is 1 with a remainder of 55.
Use 1 as the next digit of our solution. 
Result so far: 281.0
If we take 80 away from 135, we end up with 55.
Fetch the next digit (2) from the dividend, attach it to 55 and continue: 552 / 80

Let's proceed to step 6:
When dividing 552 by 80, we get 6 with a remainder of 72.
The next digit of our result is 6. 
Result so far: 2816.0
Deduct 480 from 552 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 7:
80 can be fit into 720 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 2816.9
If we take 720 away from 720, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
If we divide 0 by 80, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2816.9
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2816.9
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 2816.9, and the remainder is 0.0.
